Hello, I hope that someone can give me more info on this topic. Concerning my 04 CS, whether I'm in D or M mode, it never shifts to 1st gear. When I come to a stop, the gearing always defaults to D2 or M2. I've never seen it go into D1, and I always have to manually downshift from 2 to 1 when I am in manual mode. Is this normal? Thanks everyone.

No, this is not correct. My previous car was CS 04, i ve never had this problem. i advize you to take it to your local dealer for check. Before that check from stop if this happens in sport mode,econ etc.

It's here already several times mentioned: Cayenne in D start only in 1 gear when the engine is cold and when flooring the accelerator, with hot engine and quick and in one move, on for example a traffic light. M mode is manual shift mode, it is normal to shift in 1 gear manually. In all other cases, the Tiptronic is programmed to start in 2 gear. Normal behavior IMHO.

The only way to get it to start automatically in 1 is to turn off PSM on the dash. IF this does not happen its a sign that the transmission control unit is not the updated one it should be. These were changed under warranty way back then

This does not happen when I turn PSM off. Would Porsche still cover this under warranty? I'm at 82K miles right now.

*Just called the closest Porsche dealer, the service consultant basically tells me I'm an idiot for thinking that the TCU is outdated.
